That’s what you can see here. “Ammo,” by Sabine Pearlman, is a series of photos of perfectly bisected projectiles. All have some sort of recognizable silhouette–either the short, stubby shape of a 9 mm cartridge, the chunky rectangular body of a shotgun shell, or the long menacing lines of higher-powered ammunition–but inside, we see, each has its own unique architecture.

Pearlman happened upon the cleaved ammo last autumn, when she was touring a Swiss military bunker set deep in a mountainside in the Alps. There were 900 different types of ammunition in all. “I instantly wanted to photograph them,” Pearlman says. She convinced the munitions expert there–the one who had actually cut the bullets in half–to let her document them, and returned shortly thereafter to see it through.
